Abstract

Die Erfindung betrifft ein Verfahren und eine Einrichtung zum Behandeln von energetisch verwertbaren Reststoffen, insbesondere Shredder-Leichtmüll, die verkleinert und klassiert in Bunkern gelagert (11,12) werden. Hierbei wird

  • a) der Reststoff von den Bunkern (11,12) portionsweise einem Metallschmelzofen, insbesondere einem Elektrolichtbogenofen (40) zum Schmelzen von Stahl, zugeführt und in einem Vorratstrog (21) bevorratet,
  • b) nach vorgegebener Zeit wird der Reststoff portionsweise in eine gasdicht verschließbare Schleuse (31) eingebracht,
  • c) nach Verschließen der Schleuse (31) wird der Reststoff mit einem sauerstoffhaltigen Gas, dessen Druck höher ist als der des aktuellen Druckes am Ofenkopf (49) des Metallschmelzofens (40), beaufschlagt,
  • d) nach Erreichen eines vorgebbaren Druckes in der Schleuse (31) und nach Öffnen eines dem Ofengefäßboden (42) zugewandten Schleusenaustrittes (33) wird der Reststoff pneumatisch in den Ofenraum ausgefördert und
  • e) in die sich im Bodenbereich des Metallschmelzofens befindliche Metallschmelze (S) eingetaucht.
    • The invention relates to a method and a device for treating energetically usable residues, in particular light shredder waste, which are stored in reduced size and classified in bunkers (11, 12). Here will
  • a) the residual material from the bunkers (11, 12) is fed in portions to a metal melting furnace, in particular an electric arc furnace (40) for melting steel, and is stored in a storage trough (21),
  • b) after a predetermined time, the residue is introduced in portions into a gas-tight lock (31),
  • c) after the lock (31) has been closed, the residual material is charged with an oxygen-containing gas, the pressure of which is higher than that of the current pressure at the furnace head (49) of the metal melting furnace (40),
  • d) after reaching a predetermined pressure in the lock (31) and after opening a lock outlet (33) facing the furnace vessel bottom (42), the residual material is pneumatically conveyed into the furnace chamber and
  • e) immersed in the molten metal (S) located in the bottom area of the metal melting furnace.
